The complete mitochondrial genome of Holothuria edulis was obtained and described in this study. This complete mitochondrial genome is 15,743 bp in length and consists of 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. Except ND6 and 5 tRNAs, the others were encoded by the heavy strand. The overall base composition of the heavy-strand was 32.29% A, 15.25% G, 25.88% C, and 26.57% T, with a high A + T content of 58.86%. The phylogenetic analysis suggested that H. edulis was closest to H. pervicax. The newly described mitochondrial genome may provide valuable data for phylogenetic analysis for Holothuroidea.
